Description
-i --i -
La présente invention concerne un dispositif permettant d'augmenter la surface de contact entre une Échelle à barreaux, en aluminium à un ou plusieurs plans, et un cyprès ( cupressus sempervirens ) afin d' accroître la st6bilité de 5 l'échelle. Lors de la taille d'un cyprès en forme de " bougie ", la surface de contact entre le barreau de 1' échelle et le feuillage reste très faible, ce qui provoque une très forte instabilité, et par conséquence de grands risques de 10 chutes. Aussi, l'échelle, sous le poids d'une personne, s'enfonce dans le feuillage en l'écrasant et le 'déformant, empêchant le jardinier de réaliser correctement son travail. De plus, l'autre désagrément que l'on peut observer 15 c'est qu'il est difficilement possible de libérer ses deux mains lorsque l'on se trouve en haut de l'échelle en possession d'un outil de taille. Le dispositif selon l'invention permet de remédier à ces inconvénients. Il est composé de deux parties reli=es entre 20 elles par deux tiges filetées possédant chacune à leur extrémité inférieure une mollette de serrage. Les gouttières des deux parties du dispositif s'emboîtent entre deux barreaux d'une échelle exerçant une pression à la manière d'une mâchoire , lors du serrage des mollettes. 25 Les dimensions du dispositif sont telles, qu'elles s'adaptent à toutes les échelles "standard" qui répondent aux normes françaises. A l'extrémité de la partie supérieure du dispositif se trouve deux bandeaux concaves pouJant être en aluminium ou une autre matière (ex: sangLes), un 30 inférieur et un supérieur, dont leurs extrémités relient de deux petites tiges, soudées elles-mêmes perpendiculairement aux extrémités des deux bras de la partie supérieure. Lors de la pose d'une échelle contre un cyprès, celle-ci pourvue de ce dispositif, les deux bandeaux concaves - 2 - épousent la forme du feuillage en ne l'écrasant et le déformant que très légèrement, augmentant la surface de contact et par voie de conséquence la stabilité de l'échelle. The present invention relates to a device for increasing the contact area between a ladder ladder, aluminum in one or more planes, and a cypress (cupressus sempervirens) in order to increase the stability of the ladder. When cutting a cypress shaped "candle", the contact area between the ladder bar and the foliage remains very low, which causes a very high instability, and as a result of large risks of 10 falls . Also, the ladder, under the weight of a person, sinks into the foliage crushing and deforming it, preventing the gardener from doing his job properly. In addition, the other annoyance that can be observed 15 is that it is hardly possible to release both hands when one is at the top of the ladder in possession of a tool size. The device according to the invention overcomes these disadvantages. It is composed of two parts interconnected by two threaded rods each having at their lower end a clamping wheel. The gutters of the two parts of the device fit between two bars of a ladder exerting pressure in the manner of a jaw, when tightening the knobs. The dimensions of the device are such that they adapt to all "standard" scales that meet French standards. At the end of the upper part of the device are two concave strips for aluminum or other material (eg blood), a lower and an upper, whose ends connect two small rods, welded themselves perpendicularly. at the ends of the two arms of the upper part. When laying a ladder against a cypress, the latter provided with this device, the two concave strips - 2 - follow the shape of the foliage by crushing and deforming it only slightly, increasing the contact surface and consequently the stability of the scale.
Les dessins annexés illustrent l'invention : La figure 1 représente en coupe le dispositif de l'invention. La figure 2 représente une vue de dessus de a partie supérieure et inférieure du dispositif. The accompanying drawings illustrate the invention: FIG. 1 represents in section the device of the invention. Figure 2 shows a top view of the upper and lower part of the device.
En référence à ces dessins, le dispositif comporte une partie supérieure constituée d'un cadre en aluminium (1), de deux bandeaux concaves (2) à son extrémité, et d'une gouttière renversée (3) à son autre extrémité, puis une partie inférieure en aluminium (4) représentant une gouttière identique mais dans un sens opposé à celle de la partie supérieure. Les deux gouttières emprisonnant deux barreaux d'une échelle (5) sont reliées entre elles par deux tiges filetées (6) qui se glissent dans leurs tubes respectifs (7,8) soudés verticalement sur les gouttières. Des mollettes de serrage (9) se trouve à l'extrémité des tiges filetées, et lorsqu'on les visse, les gouttières exercent une pression entre les deux barreaux provoquant ainsi l'immobilisation du dispositif à l'échelle. Ce moyen de fixation sur une échelle permet à une personne d'utiliser ce dispositif en un temps très court et sans avoir recourt à des outils spécifiques tels que des clés ou des tournevis etc A la terminaison des deux bras (10) du cadre (1) deux embouts en aluminium (11) sont soudés perpendiculairement à 30 ceux-ci. Les deux embouts sont reliés entre eux par deux bandeaux concaves, un supérieur et un inférieur, permettant D'épouser les surfaces arrondies des cyprès lorsque le dispositif est en utilisation. - 3 - Sur la partie latérale externe d'un des deux bras (10) est soudée une petite tige en aluminium en forme de U (12) permettant de recevoir une paire de cisaille. En effet, l'outil de référence pour la taille d'arbre ou de cyprès étant une paire de cisaille, le jardinier amateur ou professionnel pourra, pour libérer ses deux mains, glisser son outil, manche vers le haut, dans ce logement prévu à cet effet. L'angulation des deux axes formée par l'ensemble des gouttières (3,4) et du cadre (1) de la partie supérieure sera de 1100 étant donné que l'angle entre le sol et l'échelle est de 70 (norme de sécurité). A titre d'exemple non limitatif le dispositif aura des dimensions de l'ordre de 40 cm de large, 30 cm de longueur 15 et 40 cm de hauteur. Ce dispositif est particulièrement destiné à augmenter la stabilité d'une échelle contre un cyprès (cupressus sempervirens) en augmentant la surface de contact entre eux. With reference to these drawings, the device comprises an upper part consisting of an aluminum frame (1), two concave strips (2) at its end, and an inverted channel (3) at its other end, then a lower part of aluminum (4) representing an identical gutter but in a direction opposite to that of the upper part. The two gutters trapping two rungs of a ladder (5) are interconnected by two threaded rods (6) which slide in their respective tubes (7,8) welded vertically on the gutters. Clamps (9) are at the end of the threaded rods, and when screwed, the gutters exert a pressure between the two bars thus causing the device to stand on the scale. This means of attachment on a scale allows a person to use this device in a very short time and without having recourse to specific tools such as wrenches or screwdrivers etc. At the termination of the two arms (10) of the frame (1 ) two aluminum tips (11) are welded perpendicularly thereto. The two end pieces are interconnected by two concave bands, one upper and one lower, allowing to marry the rounded surfaces of the cypresses when the device is in use. - 3 - On the outer side of one of the two arms (10) is welded a small U-shaped aluminum rod (12) for receiving a pair of shears. Indeed, the reference tool for the size of tree or cypress being a pair of shears, the amateur or professional gardener can, to release both hands, slide his tool, handle up, in this housing provided for this effect. The angulation of the two axes formed by the set of gutters (3,4) and the frame (1) of the upper part will be 1100 since the angle between the ground and the scale is 70 (norm of security). By way of non-limiting example the device will have dimensions of the order of 40 cm wide, 30 cm in length 15 and 40 cm in height. This device is particularly intended to increase the stability of a ladder against a cypress (cupressus sempervirens) by increasing the contact surface between them.
